"I think therefore I am" Descartes

To me this quote means that Descartes is thinking about things in life so he is alive. Basically you have to think to live. If you don't think then you're like a zombie that can't even tell his left from right. Everyone in the world thinks whether it is positive or negative thoughts. Also, everyone has different thoughts which makes them different people. For example, if we keep thinking mean thoughts then we become mean people, kind thoughts we become kind people etc... Thoughts are basically the most important things in our lives. Without them we are nothing.
